Dodge is an American brand of automobile manufactured by Chrysler Group LLC, based in Auburn Hills, Michigan. Dodge vehicles currently include the lower-priced badge variants of Chrysler-badged vehicles as well as performance cars, though for much of its existence Dodge was Chrysler's mid-priced brand above Plymouth. Founded as the Dodge Brothers Company machine shop by brothers Horace Elgin Dodge and John Francis Dodge in the early 1900s, Dodge was originally a supplier of parts and assemblies for Detroit-based automakers and began building complete automobiles under the "Dodge Brothers" brand in 1914, predating the founding of Chrysler Corporation. The factory was located in Hamtramck, Michigan, and was called the Dodge Main factory from 1910 until its closing in January 1980. The Dodge brothers both died in 1920, and the company was sold by their families to Dillon, Read & Co. in 1925 before being sold to Chrysler in 1928. Dodge vehicles mainly consisted of trucks and full-sized passenger cars through the 1970s, though it made memorable compact cars and midsize cars. The 1973 oil crisis and its subsequent impact on the American automobile industry led Chrysler to develop the K platform of compact to midsize cars for the 1981 model year. The platform and its derivatives are credited with reviving Chrysler's business in the 1980s. The Dodge brand has withstood the multiple ownership changes at Chrysler from 1998 to 2009. In 2011, Dodge, Ram, and Dodge's Viper were separated. Dodge said that the Dodge Viper would be an SRT product and Ram will be a manufacturer. In 2014, SRT was merged back into Dodge. Later that year, Chrysler Group was renamed FCA US LLC, corresponding with the merger of Fiat S.p.A. and Chrysler Group into the single corporate structure of Fiat Chrysler Automobiles.
